EngineeringFormulaIf you know forces and mass
Start with Force or Net Force, then move to Acceleration when you need the motion that force creates. Use Gravitational Force only for attraction between two masses, not everyday weight.
Engineering Mechanics
The Newtonian vocabulary - force, motion, energy, momentum - every other discipline builds on.
Force, motion, energy, and momentum are the vocabulary every other engineering discipline builds on, which is why this group exists separately from Mechanical or Civil & Structural rather than folded into either. Newton's second law, kinematics, work-energy relationships, and conservation of momentum show up in this discipline in their most direct form - Force, Net Force, Acceleration, Velocity, Free Fall, Projectile Motion, Kinetic and Potential Energy, Momentum, and Gravitational Force.
This is the discipline most likely to be a first-year engineering or physics course problem rather than a professional design calculation, and the calculators are built for that: solving cleanly for whichever variable is unknown, with a worked example showing the substitution step, not just a final number.

Which calculator should I start with?
If speed or height is known
Use Velocity, Free Fall, Projectile Motion, Kinetic Energy, or Potential Energy depending on whether the problem is motion, falling distance, launch path, stored energy, or motion energy.
If impact is the real question
Use Momentum and Impact Force together. Momentum tells you how hard motion is to stop; impact force depends heavily on stopping distance or stopping time.
